i have a 1987 4x4 pickup 22r 5 speed, all of a sudden the other day it started making a kind of rattling grinding noise in every gear except 4th. it makes no noise at idle or in 4th and it gets louder as i go faster.
i dont know much about transmissions so any ideas would be appreciated this is my brothers truck and i need to fix it because it started doing it while i drove it

 

based on the description, it aint sounding good...

got a neutral on your transfer case? (you do, even if you don't have the detent for it) It's between the 4H and 4L. Directly in the middle.

Put the TC in "N" and repeat testing process. Come back and tell me/ us what happens.

hey wait... 4th is a 1:1 so that makes me think input or output shaft bearing...(for some reason)

 

i already did the neutral thing it doesnt make any noises, my buddy said something about the 4th gear being 1:1 but i never really messed with transmissions before so i dont know much about how they work, are the input and output shaft bearings hard to replace?

 

anyone have any ideas? its still got me beat

 

I have this exact same problem. I have noise in every gear except 4th. 5th gear being the worse.

5th is also the worst for me too

 

Sorry, I don't have any ideas for your noise problem.

However, you said you need to fix it because it happened when you were driving it. Whatever happened to it, I doubt it was really your fault. More than likely, something was about ready to go anyway, you just happened to be the one driving it when it went. Unless you were jamming it into wrong gears, and stuff like that.

 

its my brothers truck but me and my dad use it way more than he does because it is our only 4x4 it will probably be more of a 3 way split on cost with me doin all the work because im the one that knows how to work on cars.

 

Ahhh, I got you. I would tell them that they can buy the parts if you're the one doing the work! Or send them the bill for your labor!

 

haha believe me i would if i could

 

No one has any idea as to what the noise could be?

 

any help out there?

 

Time to rebuild tranny

 

thats what i was afraid of i dont have the tools or money to rebuild a tranny, i guess i'll have to find a used one somewhere cheap

 

Mine does the same thing. I have been searching the internet for a fix or what the problem is. I found this... but still haven't checked it out on mine.
